✓ The short version
We ask only for your first name, last name, and email so we can save your practice progress and, if you choose, connect you with your teacher's class. Your practice data is end-to-end encrypted. We use a cookieless, privacy-friendly page-view counter and nothing else — no advertising, no third-party trackers, no selling or sharing of your information.
What we collect
The only personal information we collect is what you voluntarily provide when you create an account:
- First name and last name — so your teacher can recognize you and so the app can greet you.
- Email address — used to save your practice history across devices and to recover your account if you lose access.
As you practice, the app records your practice activity (which deals you played and how you did) so it can show your progress and, if you join a class, share your progress with your teacher. We do not collect payment information, we serve no downloads, and we ask for nothing beyond the items above.
How your data is protected
Your practice activity is end-to-end encrypted. It is encrypted on your device before it is sent to our server, which means it cannot be read in transit or at rest by anyone — including us — except you and any teacher you have explicitly chosen to share it with.
Sharing your progress with a teacher is always something you opt into by joining their class. You can leave a class at any time from your settings, which stops your teacher from seeing your progress on new work.
Analytics and cookies
We use GoatCounter, a privacy-friendly, open-source analytics tool, to count how many times our pages are viewed. GoatCounter:
- does not use cookies;
- does not collect or store personally identifiable information;
- does not track you across other websites.
It tells us only aggregate, anonymous counts such as how many people visited a page. We use no advertising networks and no third-party tracking of any kind.
How we use and share your information
We use your information solely to operate the service — saving your progress, letting you sign in across devices, recovering your account, and connecting you with a teacher's class when you ask us to.
We do not sell, rent, or trade your personal information, and we do not share it with anyone without your express consent. The only third parties involved are the infrastructure providers needed to run the service (for example, our hosting provider and the email service used to send account-recovery messages), and they process data only on our behalf.
Your choices and data removal
You can request that we delete your account and associated data at any time by emailing [email protected]. Because the platform is open source, you are also welcome to review exactly how your data is handled in our source code.
